I have almost finished Hatcher topology section $1.1$ but not $1.2$(Van Kampen's theorem) and $1.3$( covereing space)
Now my question is that
Can I directly jump into $2$nd chapter homology theory?
Will I face any difficulty in understanding if i will not read Van Kampen and covering space topics.Actually i don't want to read $1.2$(Van Kampen's theorem) and $1.3$( covereing space).I want to skip these two topics
I have seen many books of algebraics Toplogy where fundamental group chapter is not included.
Also,i want to know the about the prequisite for homology theory
